.SH "NAME"

\fBcallgrind_annotate\fR [\fIoptions\fR] [\fIcallgrind\-out\-file\fR\ [\fIsource\-files\fR...]]
.SH "DESCRIPTION"
.PP
\fBcallgrind_annotate\fR
takes an output file produced by the Valgrind tool Callgrind and prints the information in an easy\-to\-read form\&.
.SH "OPTIONS"
.PP
\fB\-h \-\-help\fR
.RS 4
Show summary of options\&.
.RE
.PP
\fB\-\-version\fR
.RS 4
Show version of callgrind_annotate\&.
.RE
.PP
\fB\-\-show=A,B,C [default: all]\fR
.RS 4
Only show figures for events A,B,C\&.
.RE
.PP
\fB\-\-threshold=<0\-\-100> [default: 99%] \fR
.RS 4
Percentage of counts (of primary sort event) we are interested in\&.
.sp
callgrind_annotate stops printing functions when the sum of the cost percentage of the printed functions is bigger or equal to the given threshold percentage\&.
.RE
.PP
\fB\-\-sort=A,B,C\fR
.RS 4
Sort columns by events A,B,C [event column order]\&.
.sp
Optionally, each event is followed by a : and a threshold, to specify different thresholds depending on the event\&.
.sp
callgrind_annotate stops printing functions when the sum of the cost percentage of the printed functions for all the events is bigger or equal to the given event threshold percentages\&.
.sp
When one or more thresholds are given via this option, the value of
\fB\-\-threshold\fR
is ignored\&.
.RE
.PP
\fB\-\-show\-percs=<no|yes> [default: no] \fR
.RS 4
When enabled, a percentage is printed next to all event counts\&. This helps gauge the relative importance of each function and line\&.
.RE
.PP
\fB\-\-auto=<yes|no> [default: yes] \fR
.RS 4
Annotate all source files containing functions that helped reach the event count threshold\&.
.RE
.PP
\fB\-\-context=N [default: 8] \fR
.RS 4
Print N lines of context before and after annotated lines\&.
.RE
.PP
\fB\-\-inclusive=<yes|no> [default: no] \fR
.RS 4
Add subroutine costs to functions calls\&.
.RE
.PP
\fB\-\-tree=<none|caller|calling|both> [default: none] \fR
.RS 4
Print for each function their callers, the called functions or both\&.
.RE
.PP
\fB\-I, \-\-include=<dir> \fR
.RS 4
Add
\fBdir\fR
to the list of directories to search for source files\&.
